To all who 01 525 may concern-1' B'eit known that we, 'HANs "H. Jnssinv and lCo'ro-i: IF. li lAiionAU, citizens of the United States, residing at Vindsor endEast i-lantl ord, respectively, in the county of Hartim'd and State o it Gonnec-ticutflmve invented a new and useful Improvement in Machines for r lpiplyin'g Powder to Printed Matter, of which theiollowing is a specificae tion.

This inventionrelates to a machine which designed-to apply powder,-such asgold, hronze or colored pigm ent to matter, for example plaintype, artistic figure-s or ornamentation, -printedstan' ped or embossed from type, plates orblooks, upon sheets or other articles.

The object of "the invention is the production of athand guided machine forsuch purpose which is simple tomanipulate, rapid, neat and efiicient in the application of POlV'fl der, economical in the use of powder, and more healthful for-the operatives than the devices previously used, in that all the surplus powder is; collectedand sdr awn into the machine and not permitted-to fly about the room in which thermachines are operated and be inhaledby the operatives.

In the machine illustrated as embodying the invention there is a rotatory pad for spreading {the powder over the matter to be illuminated and-to which the powder is "fed as is requiredirom a'reservoir and there is a rotatory suction fan which collects the surplus powder and returns'it to a receiver. Means are also ,provided "for flexiblysup portingthe machine in convenient position i or use. p p

In the accompanying drawings 2F ig. 1 shows an elevation of the structure with a portion olithe active part of the machine cut in sectionto e'xposeith'e interior. Fig. 2 shows a horizontal section on the dotted line 22 on Fig. l. v

The casing of the machine shown coniprises several parts, a skirt 1, suction chamber 2, cap 3 and reservoir 4, permanently secured together. The skirt which has an open bottom and openings through its top surrounds the powder spreading pad 5 that is preferably made of beaver fur in a common manner. The pad is fastened to the under side of a disk 6 that is flexibly mounted on a ball 7 attached to the lower end of a rotatable tube 8. Springs 9 are arranged 1m. Serial "711,619.,

bet veen the disk and tube to permit thepa-tl totip and adjust itself with'relati'ontjo the tube and the s'uiiace'to be coated whcnbei'ng used, but cause"ith'e pad'lto be 'l' o'tfaitedwith the tube. The tuhe at its lower end opens into the pad andati its upperend opens ii rte the'lower end-of the reselwoir. The powder to "be "distributed upon the printed matter is" putinto'th'e reservoir, a cover IO'beingIemovable for this purpose, and allowed to flow down through the tube to thepia d. In the neck o'itthe reservoir isa vail'vell provided with a (port and thumb 'lev v 1?. A spring-1e keeps the valve closed. Whenthe thumb lever is depressed the valveis moved so as to permit powder to pass I through itsp'ort from the reservoir into the tube and drop downto the brush. y i Surroundnw "he feed "tube is a rotatable sleeve 15, anti-i 4 provided to ensure freedom of'rotatio'n for ion bearings 16 [being the sleeve. On the sleeve "in the suction chamber is a snot-on fan 17;, The suction chanijber has a volu te shape. The fan is{-a1'-' ranged to produce a drait'of air up'thro ugh the skirt about thepadand discharge the air through the outlet 18 irom the chamber. Mounted on the outlet of the suction chamber is a framed? which supports a bjagQO. The lower end of the bag is/fastenedaround the suction chaniberoutlet and the upper end oiF-th'e bag isheldi'n -the neck 21st the top oi'the'fram'e. A removablecover 22is placed on the 'n'e clrove'r "the mouth er the a i The feed tubernear its upperend ln the cap section oftli'eslie'llhas a'pinion 23'n1esh i ingwith wlii'clri's a gear QJron-a shortarbor 25 which h as a pinion 26 engaged by a worm 27 on'the drivesh'a ftfi The drive shaft 9 iii-a3 herniated byany suitable means-and when driven, it, through the gears "and pinions mentioned, causes the rotation at relatively low speed of the feed tube and pad carried thereby. jv

On the upper end of the fan sleeve is a gear 29 meshing with which is a gear 30 on the drive shaft 28; When the shaft is running the fan is driven through these gears at a relatively highspeed.

The cap section of the shell is provided with a handle 31 by means of which the machine may be manipulated. The machine is desirably supported by a spring depending from the arm which is mounted on a standard 3-1. These means sup-port the machine flexibly in such a manner that 1t is in convenient position to be grasped by the handle and moved about for spreading the powder on the surface to be treated.

In use the handle is grasped and the valve opened to permit a quantity of the powder to pass down the feed tube to the pad. With the pad rotating it is carried down and brushed over the surface to be powdered, the powder being drawn out by centrifugal action between the interstices of the pad and distributed over the moist printed matter. As the fan is rotating at thesame time, all surplus powder is. drawn up and deposited in the bag. As more powder is needed the valveis opened. With this arrangement the desired quantity of powder is lightly brushed over the moist printed matter and the unused powder is collected so that it does not float about in the air where it is at least a source of discomfort if not a menace to, the health of the operative. When the operation is completed and the handlevis released the support lifts the machine and retains it in position for subsequent use.

The invention claimed is 1.
